2* REXXAPI.C *
3* *
4* This program adds a ZIP engine directly to the REXX language. *
5* The functions are: *
6* UZDropFuncs -- Makes all functions in this package *
7* unknown to REXX. *
8* UZLoadFuncs -- Makes all functions in this package *
9* known to REXX so REXX programs may *
10* call them. *
11* UZFileTree -- Searches for files matching a given *
12* filespec, including files in *
13* subdirectories. *
14* UZUnZip -- Unzip command-line entry point. *
15* This is functionally equivalent to *
16* using Unzip as an external program. *
17* UZUnZipToVar -- Unzip one file to a variable *
18* UZUnZipToStem -- Unzip files to a variable array *
19* UZVer -- Returns the Unzip version number *
20* *
